Dispenser/Pipettor Transfers and mixes the appropriate inoculum volume
predetermined by the test card bar code (60 µL to 300µL - see
Aliquot) to adjacent susceptibility tubes. The system includes a
container for pipette tips, a displacement pump, and various tip
mechanisms.
Disposables VITEK
®
2 disposables are pipette tips, sterile saline, test
cards, and inoculum tubes.
Disposable supplies are biohazardous after use and must be
discarded according to local laws regarding biohazardous

normal trash, etc.
Filler Station This station inoculates all of the cards in a cassette with the
suspension contained in their corresponding test tubes. It
utilizes a vacuum chamber and air pump.
Incubator The incubator contains a heater and a circulating fan used to
incubate the cards during test. The temperature is monitored
and controlled through the use of two remote precision
thermistors monitored by a microprocessor holding the card at
an average temperature of 35.5 °C.
